Hi, I increased my Levothyroxine a month ago from 150mcg three times a week/125mcg four times a week to 150mcg five times a week/125mcg twice a week. Results as follows:
Lower dose: TSH 1.3 (0.27-4.20); Free Thyroxine 17.100 (12.00-22.00); Free T3 4.94 (3.10-6.80)
Higher dose: TSH 0.899 (0.27-4.20); Free Thyroxine 16.200 (12.00-22.00); Free T3 4.49 (3,10-6.80)
Why have my FT4 and FT3 gone down in the past month while on a slightly higher dose?
My history is that I increased my dose from 125mcg to 150mcg at the end of last year and a couple of months later started having anxiety/panic attacks. I assumed I was over-medicated and reduced back down (but no blood results to confirm over-medication). Then Medichecks bloods showed that I had become hypothyroid on the lower dose and I've been gradually increasing my dose ever since, although the anxiety is still around (which may be unrelated). Other blood results (vitamins and minerals) have been fine. Are my most recent results OK? Should I leave well alone, or should I increase to 150mcg daily?
Would be really grateful for advice and any thoughts on why my thyroid hormones are now lower than before despite being on a higher dose?
